Abstract

An electric saw comprises a DC brushless motor or a DC motor. After deceleration by a two-stage planetary set, the motor drives a power plate with an eccentric wheel to rotate, and the eccentric wheel drives a connecting rod. Thus, a slide blade connecting a saw blade moves to and fro within a sliding groove frame in a manner like manual sawing. A portable and rechargeable battery is used as the power of the electric saw, which is suitable for work in a field orchard. The saw not only promotes the working efficiency, but also reduces the labor burden. Moreover, the utility model is characterized in that the saw is dismountable. When the saw blade is abraded naturally, the blade can be dismantled and replaced with a new one.

Description

A kind of power saws
[technical field]
The utility model relates to a kind of power saws, is the power supply operate as normal but relate in particular to a kind of rechargeable battery that utilizes, convenient use, the power saws that efficient is high.

[summary of the invention]
At the problem of above-mentioned existence, but providing a kind of rechargeable battery that utilizes, the purpose of this utility model is the power supply operate as normal, convenient use, the power saws that efficient is high.
For realizing above-mentioned purpose, the technical solution of the utility model is to provide a kind of power saws to comprise: CD-ROM drive motor, drive the gear train motion that is connected with saw blade, it is characterized in that: CD-ROM drive motor connects the two-stage planet group and slows down, described planetary gear and one is with eccentric power disk to be connected, its eccentric wheel connects connecting rod, and connecting rod is connected with the slide of saw blade, and described slide can move back and forth in runner frame.
Comprise four bearings on the described runner frame, slide is slided repeatedly in the centre.
Described planetary gearsets is by drive end bearing bracket, rear end cap, two-stage planetary plate and front and back gear train are formed, described CD-ROM drive motor go out axle head, be connected with first sun gear of planetary plate.
Also comprise protective cover, be fixed on the motor seat that it comprises that paster is pasted in the draw-in groove, is pressed on the slide.
Comprise that also one handle is fixed in above the motor seat, it also comprises an Aviation Connector, does the inlet of power supply.
CD-ROM drive motor can be DC Brushless Motor or the DC d.c. motor drives.
Advantage of the present utility model is: owing to utilize DC Brushless Motor or DC d.c. motor to drive, slow down through the two-stage planet group, drive one and be with eccentric power disk to rotate, its eccentric wheel is drivening rod again, thereby makes the slide that connects saw blade, in runner frame, move back and forth, formation is power supply as the operating principle of staff sawmilling with portable rechargeable battery, is fit to the operation of open-air orchard, not only raise the efficiency, and alleviate the manpower burden; Moreover another characteristics of the present utility model are that saw blade is detachable, after the saw blade fair wear and tear, can take off easily, change new saw blade.
[description of drawings]
Fig. 1 is the stereogram of a kind of power saws of the utility model;
Fig. 2 is the explosive view of a kind of power saws of the utility model;
Wherein, saw blade 11, planetary gearsets 12, CD-ROM drive motor 13, power disk 16, slide 14 and handle 15.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed structure of the present utility model, characteristics and purpose.
As Fig. 1, shown in Figure 2, a kind of power saws of the utility model comprises: saw blade 11, CD-ROM drive motor 13, slide 14 and handle 15.
Described CD-ROM drive motor 13 is connected with a motor seat 131 by driving gear set 12, described motor seat 131 comprises some screw holes 1311, be convenient to planetary gearsets 12 lockings thereon, described planetary gearsets 12 is by drive end bearing bracket 122, rear end cap 123, two-stage planetary plate 124 and front and back gear train 125 and 126 are formed, wherein, every group of planetary reduction gear ratio is 4 to 1, so two-stage planet speed ratio is 16 to 1, motor 13 go out axle head 132, be connected with first sun gear 1241 of planetary plate 124, thereby drive its rotation and become power resources, the line shaft 127 of planetary gearsets 12, passing motor seat 131 is connected with the center of a power disk 16, which is provided with an eccentric shaft 161, be inserted in dead eye 163 inner faces on the connecting rod 162, the other end of connecting rod 162, the shaft 141 of dead eye 164 1 slides 14 connects, and the other end of slide 14 has position, hole 142 and saw blade 11 can be connected and fixed by screw.
The operation principle of this power saws is: CD-ROM drive motor 13 rotates, go out axle head 132 with it and be connected 12 rotations of first sun gear, 124 driven gear groups, thereby driving the power disk 16 that is connected with it rotates, eccentric wheel 161 on the power disk 16 drives slide 14 and does motion repeatedly, thereby makes the saw blade 11 of fixedlying connected with the one end do motion repeatedly.
Wherein, also comprise a runner frame 18, comprise four bearings 181,182,183 and 184 on it, make things convenient for slide 14 to slide repeatedly, do the repeatedly motion thereby drive saw blade 11 in the centre.
Wherein, also comprise protective cover 19; after whole carriage installation, lock onto on the motor seat 131, wherein with screw; earlier paster 191 is pasted in the draw-in groove 192; paster 191 can be little stalloy, and its purpose is to push down slide, and it is slided in the middle of bearing; can not skid off, protective cover 19 also has protection and beauty function.
Wherein, handle 15 comprises upper shell 151 and lower house 152, and upper shell 151 and lower house 152 combinations can be fixed in above the motor seat 131 by screw, and it also comprises an Aviation Connector 153 down, can be used as the inlet of power supply.
Advantage of the present utility model is: owing to utilize DC Brushless Motor or DC d.c. motor to drive 13, slow down through two-stage planet group 12, the power disk 16 that drives a band eccentric wheel 161 rotates, and its eccentric wheel 161 is drivening rod 162 again, thereby makes the slide 14 that connects saw blade 11, in runner frame 18, move back and forth, formation is power supply as the operating principle of staff sawmilling with portable rechargeable battery, is fit to the operation of open-air orchard, not only raise the efficiency, and alleviate the manpower burden; Moreover another characteristics of the present utility model are that saw blade 11 is detachable, after saw blade 11 fair wear and tears, can take off easily, change new saw blade.
